25 February 2004 Flux resistance degradation in resonant grating multilayer mirror
Author Affiliations +
The operation of a polarizing grating laser mirror relies upon the coupling of the undesired polarization to one mode of the multilayer mirror. This is accompanied by an increased electric field in the mirror, thus to a decrease of the damage threshold by a factor 50. The damage threshold of the grating multilayer for the uncoupled lasing polarization is as much as 80% of that of the gratingless multilayer. The laser damage threshold tests have been made on a grating multilayer of SiO2/HfO2 deposited by sputtering.
